Problems solved by technology

[0012] 1. In order to support two-way intercommunication, the soap interface is not consistent with the http request and response, which makes the protocol implementation complicated and difficult to understand
[0013] 2. Found the shortcomings of TR069 in the transport layer, it is difficult to traverse NAT, and the signaling transmission is slow
[0014] 3. The message is bloated

Embodiment Construction

[0065] MQTT is a lightweight broker-based publish / subscribe message transmission protocol. The design idea is open, simple, lightweight, and easy to implement. Provides one-to-many message publishing, decoupling applications, and message transmission for load shielding. Using TCP / IP to provide network connectivity, NAT traversal, real-time signaling sending and receiving can be maintained with minimal overhead.

[0066] There are three identities in the MQTT protocol: publisher (Publish), broker (Broker) (server), and subscriber (Subscribe). Among them, the publisher and the subscriber of the message are both clients, the message broker is the server, and the message publish can be the subscriber at the same time.

[0067] The message transmitted by MQTT is divided into two parts: topic and payload.

[0068] Topic, which can be understood as the type of message, after the subscriber subscribes (Subscribe), it will receive the message content (payload) of the topic

Abstract

The invention discloses a remote terminal management method based on the MQTT transmission protocol. The http protocol is replaced by the MQTT protocol, the authentication based on the MQTT protocol is used for authentication, the load of the MQTT is used for the soap message transmission, and the topic is used for the receiving object sent. subscription mechanism. The MQTT protocol provides TCP persistent connections, and subsequent protocol signaling of TR069 can be transmitted through the MQTT protocol. The invention improves the reliability of TR069 messages; improves the rapidity of TR069 messages, and can achieve real-time message transmission through the long connection of MQTT; improves the timeliness and availability of management equipment, and can achieve real-time operation for equipment management and update; supports TR069 traversal nat does not require other equipment support such as traversing tunnels; based on the MQTT protocol, it is easier to understand and implement the TR069 protocol.

Description

technical field [0001] The invention relates to the technical field of remote terminal management, in particular to a remote terminal management method based on the MQTT transmission protocol, especially a TR069 protocol remote terminal management method. Background technique [0002] The full name of TR069 is "User Terminal Equipment Wide Area Network Management Protocol (CWMP)". It can flexibly and conveniently manage a large number of IP terminal devices such as VoIP and IPTV. The connection model is flexible, allowing both the management side and the terminal to initiate connection requests; rich in functions, software upgrades, and business push, the Server / Client (Agent) mode is adopted. The current basic sub-model of TR069 is shown in Table 1 below.
